Entropion is a condition where the eyelid, usually the lower eyelid, turns inward toward the eye.
This causes the eyelashes and skin to rub against the surface of the eye, leading to irritation, redness, watering, and pain.
If not treated, entropion can damage the cornea, but it is often effectively corrected with surgery.
Ageing – weakening and loosening of the eyelid muscles and tissues (most common cause)
Muscle imbalance or spasm – causing the eyelid to roll inward
Scarring of the eyelid – from injury, burns, infection, or previous surgery
Chronic eye inflammation or irritation – leading to changes in eyelid position over time
Congenital entropion – present from birth due to abnormal eyelid development
Treatment for entropion depends on the severity of symptoms and the underlying cause.
In the short term, lubricating eye drops, ointments, or taping the eyelid may help protect the eye and relieve irritation.
For a long-term solution, surgery is the definitive treatment, correcting the eyelid position so the lashes no longer rub against the eye and preventing damage to the cornea.
